Builds custom Vega and Vega-Lite visualizations in Kibana using ES|QL data sources, which means you can create charts beyond what Lens offers. Requires Kibana 9.4+ or Serverless. The skill handles the full workflow: creating visualizations from JSON specs (via stdin, no temp files needed), managing dashboards, and positioning panels on Kibana's 48-column grid. Worth noting the layout guidance is quite detailed, with specific height recommendations and above-the-fold calculations for different screen resolutions. If you're hitting the limits of standard Kibana charts or need programmatic dashboard layouts, this gives you the Vega escape hatch with reasonable guardrails.
